Since the encampment is soooooooo big and complexed I've decided to make a rough outline of it.
The Encampment is mostly east-west and north-south. To find your way out of the encampment, just keep going s, or e. But there are two places most likely to get lost in: the Stables, and the Fenced Area. A ne-sw and a se-nw road borders the two sides of the Stables. You might be wondering where the exit is in the se part of the Stables, but the exit is attucally a few ne of that area. You can also fall into the Fenced in Area. The ONLY exit out though is in the south at 'X'.
